In plants, the topological organization of membranes has mainly been attributed to cell wall and cytoskeleton. Additionally, few proteins, such as plant-specific remorins have shown function protein lipid organizers. Root nodule symbiosis requires continuous membrane re-arrangements, with bacteria being finally released from infection threads into membrane-confined symbiosomes. We found that mutations in symbiosis-specific SYMREM1 gene result highly disorganized perimicrobial membranes....
Abstract Organization of membrane topologies in plants has so far been mainly attributed to the cell wall and cytoskeleton. Taking rhizobial infections legume root cells, where plasma membranes undergo dynamic large-scale topology changes, as an initial model, we challenged this paradigm tested whether additional scaffolds such plant-specific remorins that accumulate on highly curved often wall-less domains, control local dynamics. Indeed, loss-of-function mutants remorin protein SYMREM1...
